The only reason why I used (nav/go-to ::views/content-page composite-view) was that, when we used (browser click ::views/content-tab) then on (browser getAttributes locator)  it was unable to fetch  all/updated attributes, here the attribute being @disabled='disabled' was not being fetched at all. 

I thought navigating through top-level would help solve an it did, any-ways let me try the above suggested one.
